An apparatus and method for converting hydrazine, substituted hydrazines and/or other nitrogen-containing explosive materials, particularly unsymmetric dimethyl hydrazine (UDMH), to ammonia or ammonia and the corresponding amines by hydrogenation are disclosed. The hydrazines are diluted with a suitable carrier fluid, preferably water, mixed with hydrogen, then hydrogenated in a catalyst reactor, followed by separation of the commercially valuable ammonia and amines. Separated carrier fluid and hydrogen gas may be recycled in to the process to conserve energy and reduce waste. Recycled carrier fluid may be used to preheat the diluted hydrazine prior to hydrogenation. Ammonia may be dissociated and the resultant hydrogen recycled into the hydrogenation process. The apparatus is sized for disassembly and transport for shipping to hydrazine disposal sites.
